RENESAS · DC-DC Converters · SOIC-8
ICL7660ACBAZA from RENESAS, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection on the ICL7660A (this is the BOOST pin only on the ICL7660S). |
| 2 | CAP+ | passive | Positive terminal of the charge-pump capacitor C1, whose + terminal must connect here when using polarized capacitors. |
| 3 | GND | power_in | Ground; the + terminal of reservoir capacitor C2 connects here, and the output (pin 5) must not go more positive than GND or latch-up will occur. |
| 4 | CAP- | passive | Negative terminal of the charge-pump capacitor C1; an external Schottky diode from VOUT to CAP- may be needed to prevent latchup when the input is above 5V with a rise rate over 2V/µs. |
| 5 | VOUT | power_out | Negative output voltage (-1.5V to -12V for a 1.5V to 12V input) connected to reservoir capacitor C2. |
| 6 | LV | input | Low-voltage control: tie to GND to bypass the internal regulator for supplies below 3.5V, and leave open for supplies above 3.5V to ensure latchup-proof operation. |
| 7 | OSC | input | Oscillator terminal: nominal 10kHz at 5V, can be lowered with an external capacitor or overdriven by an external clock through a 1k series resistor. |
| 8 | V+ | power_in | Positive supply input, 1.5V to 12V operating range (13.0V absolute maximum). |
